Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white ...

What happens to planets as their stars age and come closer to death? This is what a recent study published in the Monthly Notices of the Royal Astronomical Society hopes to address as a team of ...

New observations of a nearby red giant star suggest that a long-standing explanation for how giant stars spread life’s essential elements through the galaxy may be incomplete. Starlight pushing on gra ...

Planets orbiting dead stars known as white dwarfs might be able to remain habitable thanks to general relativity subtly altering their motion. When stars like our sun run out of fuel, they expand and ...

New observations of the red giant star R Doradus suggest starlight alone cannot drive stellar winds that spread key elements through the galaxy.

"The combination of extreme disk size, strong asymmetries, winds, and potential planet formation makes it the perfect ...
